The U.S. Olympic Committee will choose from among Boston, Los Angeles, San Francisco and Washington if it decides to bid for the 2024 Olympics.

“We’re extremely pleased with the level of interest U.S. cities have shown in hosting the Games,” USOC CEO Scott Blackmun said, according to TeamUSA.org. “Boston, L.A., San Francisco and Washington have each given us reason to believe they can deliver a compelling and successful bid, and we look forward to continuing to explore the possibilities as we consider 2024.”

Dallas and San Diego were also thought to be in the running for the potential U.S. bid. The USOC has said it hopes to decide if it will bid and which city by the end of the year. Other bids could come from places such as Paris, Rome and a South African city.

“We would like to express our gratitude to the cities of Dallas and San Diego, which will not be moving forward in the bid process,” said USOC chairman Larry Probst said. “Dallas had a great bid and matching leadership, along with a well-established sporting community. We have no doubt about the ability of Dallas to host the Olympic and Paralympic Games, and look forward to working with them in the future to enhance the international awareness of the city. Also, we very much appreciate the high-quality proposal from San Diego, a city that truly embraces sport and has a long history of supporting Team USA.”

The International Olympic Committee will vote on the 2024 Olympic host city in 2017.

The USOC’s 2024 process began with letters sent to 35 mayors in February 2013 and has been kept private to encourage participation from the cities.

The U.S. has not hosted an Olympics since the 2002 Salt Lake City Winter Games (its last Summer Games were Atlanta 1996) and is in the midst of its largest gap between hosting since the 28-year stretch between 1932 and 1960.

Los Angeles is the only city among the four finalists to have hosted an Olympics, in 1932 and 1984. The USOC chose New York over San Francisco for its 2012 bid that ended up losing to London. A 2016 Chicago bid fell to Rio de Janeiro.

The next steps for a USOC bid team will be to perform deeper due diligence on the short list of cities. The USOC wants to make sure each city can deliver Games essentials and big-ticket items such as an Olympic Stadium, Olympic Village and media centers.

The bid team will visit the short list of cities and provide an update to the board of directors at a September meeting.
